Your dad never cared about sparing your feelings—he cared about making sure you were ready for the real world.

The Dad Test brings that same tough-love energy to your startup ideas. It’s a practical, no-nonsense guide for founders, creators, and side-hustlers who are done with sugarcoated feedback and startup theater. This book helps you ask sharper questions, face harder truths, and build something that actually works—because the market won’t pull its punches, and neither should you.

If The Mom Test taught you how to talk to customers without getting lied to, The Dad Test shows you how to challenge assumptions, pressure-test your idea, and stay grounded through every messy stage of building. It's a straight-talking manual for anyone who wants clarity, not compliments.

Inside, you’ll learn how to:

• Avoid the trap of meaningless praise
• Spot the difference between curiosity and real customer commitment
• Build MVPs that people actually use (and pay for)
• Recognize when you're being lied to—politely
• Validate your business idea with hard evidence
• Know when to pivot, when to push forward, and when to walk away

Whether you're navigating early-stage customer discovery, chasing product-market fit, or preparing to pitch investors, The Dad Test gives you the clarity and confidence to move forward—with your eyes open.

Looking for a real-talk startup book that cuts through the fluff?
This is the one. Perfect for entrepreneurs, product builders, bootstrappers, and anyone serious about building something that works. If you're tired of echo chambers and ready for practical, founder-focused advice that doesn't hold back, The Dad Test is your next must-listen.

Because if your idea can’t survive a conversation with your dad… should you really be betting your future on it?
